Hi all,I've been using my HP APS to profile our collection of studio monitors , and I just started doing a new set of profiles throughout the studio.

The profiles have a distinctly "green tint" and do not look normal at all. In the past, this wasn't the case. Of course, system software changes, and so does the HP APS which is now v1.41 for Apple Mac. I did get a profile on one iMac that came out looking right (usual), but 4 other monitors have a distinctly green tint to them.

I tried going onto the HP website, and all I can say is why not parachute yourself into Afghanistan for a similar experience?

I have not seen an issue like that with two APS pucks and they both give similar results. On Windows though. Right now I use them with ArgyllCMS/DispcalGui + a correction matrix made with an i1 Pro which improves at ;least the wide gamut monitor control. There is a choice in the main APS window where you can select what ICC version (2 or 4) you want to create. It might make the difference in Leopard OSses if you stay with version 2 profiles.

If not you could try Dispcalgui with the HP branded i1Display II from the APS package. You would need the ArgyllCMS modules and use the Argyll driver for the puck. If the puck has problems it should show similar problems with that software.

The APS puck is a re-branded X-Rite i1D2. So you might get some useful feedback on it by running it through X-Rite's i1Diagnostic app. (You'll have to try it to see if it's compatible.) This is a free utility that runs the puck through its paces, gives some raw numbers and give you a pass or fail on the instrument. It is not as if you can totally depend on its conclusion, but it's a useful piece of information.http://www.xrite.com/product_overview.aspx?ID=766&Action=support&SoftwareID=506

Hello,Thanks so much for the link to the APS puck testing software. "i1Diagnostics 2.5.1" works, and my device passes all the tests! I'm stumped as to why this is behaving as it does. This Greenish Tint is just not right.

All the LCD screens I am testing are very old, and so far the youngest LCD screen is the only one giving me a profile that looks right.

During the APS profiling, 10 patches into the profiling (Create Monitor Profile "Optimizing"), the entire screen including the screen elements of the software (an oblong navigation blob with Home & the L & R arrows that is sorta shiny silver) picks up a definite greenish tinge.

I did an experiment and before profiling I used Apple's Display Calibrator Assistant to set the White point to D50, & Gamma to 2.2, and then when I ran the APS profiling the "greenish tint" was less than before, but is still evident.

I will play with all this later, but I thank you for helping me verify that the puck is not damaged.

I am wondering if I need to profile in safe boot mode? Seems to be something going on at a different level. Back in the days of Classic, I remember fixing odd issues by running a "clean system" without extensions.

Today, I think I will create a new administrator user and try profiling again.
